ZWO ASI2600MC Pro Duo Cooled Colour Deep Sky Camera with built-in Guiding Sensor
The ASI2600MC Duo combines an imaging and guiding sensor into one compact body. The main sensor is a Sony IMX571, 23.5mm x 15.7mm, coming with a native 16bit ADC, 14 stops dynamic range and 3.76um square pixel array. The readout noise is as low as 1.0e, and the full well capacity reaches an incredible level of 80ke.
The guide sensor is a type 1/1.8 SC2210 with excellent NIR sensitivity. The sensor size is 7.68mm x 4.32mm. It has 4umx4um pixels with an array of 1920x1080 and a full depth of 8780e.
The stars in the corner of the guide images affected by reducers back focus distance might not be very round. It is not due to the sensor tilt and will not affect normal use.
Traditional CMOS sensors produce a weak infrared light source during operation quite often seen in the corner of uncalibrated images. It is the tell-tale sign of amp glow. As the ASI2600MM Duo uses zero-amp glow circuitry, you won’t have to worry about amp glow even when using high gain, long exposure imaging.
Thanks to the compact design, the ASI2600MC Duo only needs one USB cable for control. It reduces potential cabling issues and improves setup speeds. You don't need a separate OAG and guide camera.
Anti Dew Heater
There is a polyimide heater completely fitting the protective window in the ASI2600MC Duo camera. It can help avoid any potential annoying dew or icing issues depending on the environment in which you capture images.
The power of the heater is around 5W. You are free to turn it off anytime in your photography software if you want to save power.
2 Stage TEC Cooling
Thanks to the two-stage TEC cooling, ASI2600M Duo can lower the CMOS sensor temperature to more than 35 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.
*The Delta T 35℃ is tested at 30℃ ambient temperature. It might get down when the cooling system is working for a long time. Also, as the ambient temperature falls, the Delta T would decrease.
